Batteries have always presented the same problems of weight, safety, and cost. In racing, aerospace, and advanced technology industries, weight and safety present the two biggest challenges. Braille Battery’s solution is developing lighter, more powerful batteries to suit the needs of these markets. Braille Battery’s Advanced AGM batteries have allowed for more power, safer design and less overall weight than the batteries they replace, as the performance leader in the 12 volt sealed AGM (lead-acid) marketplace.

Sealed Valve Regulated Design

Completely eliminates acid spills and corrosion on terminals. Environmentally safe and does not need filling or maintenance.

Green Friendly

A manufacturing process with the highest concern for the environment and quality. Recycled lead, plastic, and stainless steel ensure we’ll have a future to race towards.

Stainless Steel Terminals

Allow higher bolt torque and help keep your battery connected even in high vibration environments.

Dual Terminals

Allow battery to be mounted in a variety of positions, vertically or horizontally, and are also removable.

At under 22 pounds, the B3121 is our lightest do eveything battery yet. Using our Advanced AGM racing technology we have put a lot of power into a very small package. With 1380 pulse cranking amps this has enough power to start more than any other battery in its weight class. This is the perfect model for those who want to shave half the weight of a stanard Group 34 battery and still have enough power to crank over a V8 engine. Used in everything from large Harley Davidsons to Corvettes & Vipers. (Note: while high in cranking amps, make sure battery has enough capacity for the vehicle intended to be used in)
